Hi everybody,

Dann has now compiled a faster and Cygwin-free executable of Glaurung 0.2.1. It can be found on Dann's FTP site or on my Glaurung page.

I noticed something strange while trying to benchmark/compare your old cygwin build and Dann's new build.

It appears that Dann's windows build doesn't respond to "stop" during infinite analysis when run from the commandline, even though it seems to work fine under arena. In fact, in arena's engine debug, you can clearly see glaurung responding to "stop".

Here are the steps I used:

uci
position startpos
go infinite
(wait until depth 12 or so)
stop

But ultimately I just had to kill the program since it wouldn't stop.

Interestingly, I observed similar behavior when compiling fruit with a couple windows compilers (mingw, vctoolkit). Fruit also wouldn't respond to "stop" from the commandline.

Any thoughts? Maybe I'm just misunderstanding the UCI protocol?

Do you have any numbers? It would be interesting to see how much faster Dann's build is.

Very strange. You are not misunderstanding the UCI protocol, the engine is really supposed to stop thinking immediately when receiving the 'stop' command. The Linux and Mac OS X versions of Glaurung do respond to the 'stop' command when running from the command line, and if I understand you correctly the Cygwin executable for Windows also does. This makes me believe that the behaviour you observed is caused by the different code used for input polling during the search in Dann's compile. The OS X, Linux and Cygwin executables uses the select() function for polling, and this function does not exist in Windows (IIRC). Dann has therefore replaced my polling code with some Windows-specific code which I don't understand at all in his Glaurung binary. Perhaps this Windows-specific code for some reason behaves differently when running from the command line than when running from a GUI like Arena.

This is nothing more than a guess, however, and it is very possible that I am entirely wrong. I think we need an explanation from someone with greater Windows expertize before we can say something definite about the strange behaviour you observe.

So it seems that Dann's is about 7-8% faster (372k vs 347).

I agree that the i/o handling must be different when executing in a command shell (vs having standard input/output mapped to something else by arena). I'm not a windows programmer either, so my only hunch is that it has something to do with different blocking or buffering or something else.

The 358k seems to fall right between Tord's and Dann's nps. (As a side note, the uci "stop" command doesn't seem to work from the commandline with this build either.)

Thanks Michael.

Oh well.

Hi Michael,

Thanks for the benchmarks! The difference between the Cygwin and MSVC executables is smaller than I expected. Evidently gcc is quite good!

Unfortunately, there is one thing which worries me. The node count is different in all three executables, and the MSVC executable even has a different score and PV than the two others. Were all three tests done with the same hash table size? If they were, I'm afraid I have a nasty bug to hunt down.

Maybe your random code behaves differently in different environments? I don't now what you're using but just a hint

Some notes:

(1) definitely seems fastest--382k (bryan) vs 372k (dann) vs 247k (cygwin)

Finally, a disclaimer: these tests are just tests from the start position, so they might not representative of the speed over all positions encountered over a game.

Hi Tord,

Regarding your question about hash size and different node counts...

Each run uses glaurung's defaults. But I noticed an interesting thing. All the node counts for the early iterations are identical. And Dann and Bryan only diverge after depth 12. Could it be that some of your info strings are sent based on elapsed time? Or are they only sent when the pv changes?

Michael

Hi Michael,

First of all, thanks for repeating your benchmark with Bryan's executable! I will replace the Windows download on my home page tonight or tomorrow.

The info strings with a PV are always displayed at the exact moment when the PV changes. The elapsed time should not have any influence at all. Peter's guess that it has something to do with random numbers also cannot be correct. It looks to me like the only possible explanation is a bug.

Hi Tord,

it may not be of any use any longer, but I have some outputs
for BH and DC versions nevertheless. (Athlon XP 1,67GHz, 128MB hash for each engine,
Arena1.1, four positions tested, engines got restarted after every position, hash was cleared.).
Bryans version seems to be about 3%-5% faster, at least on my AMD.
(Btw: Many thanks to those who compile Crafties, Glaurungs, Fruits... .!)

Hi Tord,

it may not be of any use any longer, but I have some outputs
for BH and DC versions nevertheless. (Athlon XP 1,67GHz, 128MB hash for each engine,
Arena1.1, four positions tested, engines got restarted after every position, hash was cleared.).
Bryans version seems to be about 3%-5% faster, at least on my AMD.
(Btw: Many thanks to those who compile Crafties, Glaurungs, Fruits... .!)

Thanks, Bryan!

What compiler did you use?

If somebody can test Bryan's executable and confirm that it is indeed faster than Dann's, I will replace the Windows executable on my home page.

Tord

Microsoft Compiler, No code changes nor special inlining (Like I do with Crafty) was used. Let me know when you have an new version I would be more than happy to compile it for you.
